Opis:
The needles of the Aleppo pine (Pinus halepensis) (PA) are very abundant in the forest of the National Park of Tazekka (Ta-za-Morocco) and are unexploitable. Moreover, they constitute a potential danger because they facilitate the outbreak of wildfires. To solve this problem, we have considered turning these needles into a biomaterial that could be used as raw material for different uses, such as wastewater treatment. The biomaterial of the Aleppo pine is obtained from its needles which are harvested in spring, dried, cut, crushed, and sieved. The powder obtained is analyzed before and after the extraction of essential oil. The physicochemical and spectroscopic analyses show that this biomaterial is porous, hygroscopic, slightly acidic, moderately moist, and not very conducive. Its average density in the anhydrous state is 0.6. It is rich in carbon (79.91%) and oxygen (18.91%) in the form of aromatic compounds and ketone imprints; thus, relating the presence of cellulose, pectin, lignin, and hemicellulose. Its composition in mineral elements (Na, Mg, Ca, K, Cl, S) is deficient. Gas chromatography-mass spectrometry (GC-MS) analysis of the oils extracted from the needle powder relates that it is a complex mixture of bioactive compounds such as mono-terpenoid α and β-pinene hydrocarbons. These results show that our biomaterial can be used as an adsorbent in wastewater treatment and the extracted essential oils can be used in the pharmacological, agro-food field.

Opis:
The effect of the amount of pine needle oil on the properties of rigid polyurethane (RPUF) foams was investigated. The influence of pine needle oil content on the cellular morphology, physical, mechanical, and antibacterial properties of RPUF was evaluated. The addition of pine needle oil had decreased the dynamic viscosity and processing times of polyurethane (PUR) systems. It was found that the foams containing 5 wt % of pine needle oil had better mechanical properties, e.g. compressive strength, flexural strength, and impact strength. RPUF containing the highest concentration of pine needle oil, such as 15 wt %, possessed improved antibacterial activity against E. coli and S. aureus. This study confirmed that the use of pine needle oil is an effective approach to the production of RPUFs with antibacterial activity.
Zbadano wpływ dodatku olejku sosnowego na właściwości użytkowe sztywnych pianek poliuretanowych (RPUF): strukturę, właściwości fizyczne, mechaniczne i antybakteryjne. Układy poliuretanowe (PUR) modyfikowane dodatkiem olejku sosnowego charakteryzowały się mniejszą lepkością dynamiczną oraz krótszymi czasami syntezy niż układy bez dodatku. Najlepsze właściwości mechaniczne, w tym m.in. wytrzymałość na ściskanie, zginanie trójpunktowe i udarność, wykazywała pianka poliuretanowa zawierająca 5% mas. olejku sosnowego. Najlepszymi właściwościami antybakteryjnymi (względem E. coli oraz S. aureus) odznaczała się pianka zawierająca 15% mas. olejku sosnowego. Stwierdzono, że modyfikacja układów poliuretanowych dodatkiem olejku sosnowego umożliwia otrzymanie RPUFs o właściwościach antybakteryjnych.

Opis:
The anatomical and morphological diversity of Scots pine (Pinus sylvestris L.) needles was investigated in nine Polish populations grown on the experimental plots at the Forest Experimental Station of the Warsaw University of Life Sciences – SGGW (Rogów, Central Poland). The experiment started in 1966 and the needle samples were collected from the trees cut down during the thinning treatment in 2016. The following needle traits were measured: (1) length, (2) width, (3) thickness, (4) cross−sectional area of the transfusion tissue, (5) epidermis thickness, (6) width to thickness of the needle cross section ratio, (7) distance between the vascular bundles, (8) number of resin ducts, and (9) length of the needle scales. The results showed that trees from the provenances differ with respect to the studied needle features, however, the differences, for individual traits, are relatively small and in most cases are statistically insignificant as measured by the Kruskal−Wallis test. Statistically significant differences (p<0.05) were found only in case of such features as the number of resin ducts and the length of needle scales. The results may suggest that the environmental conditions of the Polish lowland are not sufficiently diversified to induce clear differences between the individual morphological and anatomical traits of pine needles. However, despite the relatively small differences between the studied populations regarding individual traits, the use of the UPGMA (Unweighted Pair Group Method with Arithmetic mean) dendrogram, taking into consideration the combined effect of all the examined traits of needles, allowed to separate geographically the tested Polish provenances into three groups: I – mid−western (Rogów, Bolewice, Spała, Karsko, Gubin, Tabórz), II – north−eastern (Rospuda, Starzyna) and III – south−eastern (Janów Lubelski). It is suggested that this may be related both to the ability of Scots pine to adapt to local conditions as well as the possibility that the geographical groups of tested populations originated from three different main glacial refugia.

Opis:
The main aim of this study was to describe the variation between the populations of the dwarf mountain pine Pinus mugo Turra based on the morphological and anatomical traits of their needles, and to investigate the relationship between the observed variation and environmental conditions (altitude and substrate).Two-year-old needles were collected from 180 individuals of six populations of P. mugo growing in the Tatra Mts. Two populations were classified as dense, located at 1360–1450 m altitude, and the remaining four formed loose clusters and were situated at 1500–1650 m altitude. Four of the populations are growing on granite and two on a limestone substrate. The natural variation of 10 morpho-anatomical and 3 synthetic needle traits was measured. In addition to descriptive statistics, the analyses of variance (ANOVA) with a Tukey test and principal component analysis were computed. We also estimated Pearson correlation coefficients for the examined needle traits and altitude as well as substrate. Our results indicate that the P. mugo populations differ significantly with regard to the investigated traits for which the Trzydniowiański Wierch population was the most distinct. The observed pattern of variability is largely caused by differences in stomatal traits and these features are positive correlated with altitude. Additionally, populations growing on granite have larger values for most of the examined traits compared to populations growing on limestone.

Opis:
Scots pine (Pinus sylvestris L.) is one of the most widespread forest trees in the world, ranging from southern Mediterranean mountains to eastern Siberia. 30 trees of Scots pine from the Miłomłyn Forest District were analyzed in terms of 7 nuclear and 8 chloroplast microsatellite DNA loci as well as 7 morphological needle traits. Nuclear microsatellites (Simple Sequence Repeats) have proved to be useful in studying phylogeographic and gene flow patterns in conifers and are being used to infer the demographic history of tree species. A population’s genetic diversity, in fact, represents an important criterion which could be applied in planning future forest management and breeding. Additionally, many elements of Scots pine morphology, including needle traits, are subject to environmental modification. However, the adaptability of those traits remains, to some extent, under genetic control. The trees we investigated here are called Tabórz pine located in the northeast of Poland. This population is described as one of the best in Poland and even in Europe regarding bio mass production, ductility and wood quality. The aim of the study was to determine variation and genetic structure within this population. An analysis of phenotypic differentiation showed that the traits which differed the most between individuals were needle length, the number of serrations per 2 mm of needle length along the right edge and the number of stomatal rows on the convex side of the needles. In Tabórz pine, we detected 30 different genotypes with 87 alleles as well as 28 haplotypes with 30 alleles. We also revealed a slight excess of homozygotes, but the population is still in Hardy-Weinberg equilibrium. The Scots pine population from Tabórz furthermore showed a higher level of genetic diversity compared to stands from other Polish and European regions. This diversity may be the main factor impacting on the population’s wood quality and its breeding value.

In the late 18th and early 19th c., a drastic reduction in the area of forests due to their excessive exploitation occurred in Europe, which gave rise to the birth of afforestation efforts. The chemical composition of plants, including trees, depends on the many biotic and abiotic environmental factors. The aim of this study was to determine the content of some nutrients in needles and bark of Scots pine (Pinus sylvestris L.), leaves and bark of silver birch (Betula pendula) and Norway maple (Acer platanoides L.), depending on their location. The content of phosphorus, potassium, sodium, calcium and magnesium depended on a plant species, plant organ and the location of sample collection. The leaves of silver birch, compared to its bark, contained ten-fold more potassium and six-fold more phosphorus and magnesium. The content of phosphorus was the highest in silver birch leaves in the center of Olsztyn. The highest potassium content was observed in silver birch leaves and Norway maple bark in the center of Olsztyn. The calcium content was the highest in the leaves and bark of maple trees growing near State Road 51 and in the leaves of this species in the city center. The highest sodium content was detected in the leaves and bark of most tree species growing along State Road 51 and in the center of Olsztyn.

Mutational witches’ brooms (WBs) in conifers are widely used in landscaping. However, there have been few WB morphology and anatomy investigations. The needle structure of witches’ brooms and normal crown (NC) in Pinus sibirica clones was studied, using light microscopy technique. The aim was to compare the needle structure in WBs and NC and to reveal the effects of the mutation on the needle traits. Three WB and NC pairs of clones from the same trees were used in the study. WBs in the parental trees were characterized by different density in the affected part of the tree. In all pairs, WB needles were shorter and thinner than in NC. In contrast to NC needles, WB needle length was positively correlated with resin duct total area and width of endodermis cell. Thus, the affected needles had a changed structure, and the effect of the mutation was determined by mutation expression.

Opis:
Modern forestry management should be based on the principle of sustainability.In order to preserve habitat productivity, the amount of nutrients removed from the environment along with forestry products must be taken into consideration. This study shows the exact concentrations of chemical elements in different tree parts of Scots pine, growing on poor soils in north-western Poland. The observedvalues were compared to the values found in literature. In addition, the relationship between the concentrations of elements and stem diameter or stand density was researched. The highest concentration of chemical elements was observed in the needles (C, N, P, K, Mg, S, Mn, Na, Fe) and the lowest (C, N, P, S, Cu, Na, Ni, Pb, Zn, Fe) in the stem wood. Most of the macronutrients (P, K, Ca, Mg and S) reached optimal values, with the exception of N showing a deficiency, especially in the needles. The relationship between the content of elements and DBH or stand density was rather weak, and in both cases, negative.

Opis:
The synergistic effect of ammonium polyphosphate (APP) and boric acid (BA) on the flame retardancy and thermal degradation of pine needles was investigated. Thermogravimetric analysis (TGA) showed that the presence of an ammoniumpolyphosphate and boric acid system increased the char residue and decreased the pyrolysis temperature of the pine needles. The derivative thermogravimetric analysis (DTG) showed that the ammonium polyphosphate and boric acid had shifted the degradation peaks of the pine needles to lower temperatures. The cone calorimetry test results showed that the values of HRR, THR, SPR, TSP and the mass loss (%) of the pine needles treated with ammonium polyphosphate and boric acid (APP/BA = 3/2)were significantly lower than the other samples. Therefore, the APP and BA system had a better effect on the pine needles overall than the APP alone.

It was found that at the same age and in the same climatic conditions Scots pines from former agricultural land had larger stem dimensions and needle sizes as compared with the trees growing on forest land. These results lead to an interesting conclusion connected with future afforestation and reforestiation in the Krynki Forest District.

Opis:
To evaluate the geographic variability of Pinus sylvestris populations seven morphological traits of needles of pines from IUFRO 1982 provenance trial have been analyzed. The studied populations originated from northern (>55°N in Russia, Sweden and Latvia), central (55-47°N in Poland, Germany, Belgium, France, Slovakia) andsouthern (<47°N in Hungary, Bosnia, Montenegro andTurkey) European ranges of Scots pine. The analyzedprovenance trial experimental areas were locatedin Kórnik (western Poland) andin Supraśl (north-eastern Poland). The greatest variation was found in needle length and number of stomata rows on the flat and convex side of a needle, whereas number of stomata per 2mmof needle length on flat and convex side of a needle was stable, with minor interpopulational variation. Biometrical analyses revealed a significant population × location interaction anda geographical pattern in interpopulational differentiation in both experimental sites, with the northern andsouthern European Scots pine groups of provenancesdiffering significantly from the group of central origin. The results obtainedare compatible with previous results of studies on provenance variability of the Scots pine from IUFRO 1982. In the light of available data, the influence of the Balkan glacial refugia of Pinus sylvestris on a present genetic diversity of this species in Europe and the reconstruction of Scots pine migration routes after the last glacial period are discussed.

Opis:
The taxonomic position of the population of tree-like, mostly polycormic individuals of pines from the Mshana peat bog in the Gorgany Mountains (East Carpathians, Ukraine) has been studied on the basis of the morphological characteristics of cones and needles, and anatomical characteristics of the needles. These features have been compared with the surrounding Pinus mugo population as well as P. uliginosa, P. mugo, P. sylvestris and P. uncinata from natural populations of the taxa. Tree-like individuals were found to have the most similar needles to P. uliginosa, but most similar cone characteristics to P. mugo. It was concluded, that the tree-like population has a relic character and can present the trace of the early migration of P. uliginosa from the West and its hybridisation with P. mugo.
